Evaluation of heavy metals content were perfumed in samples of cereals crops grown around the industries in Singrauli region for the two sequential experimental duration of 2020-2021 and 2021-2022. There are four cereals crops Paddy (Oryza sativa), Wheat (Triticum aestivum), Maize (Zea mays), and Jowar/Sorghum (Sorghum vulgare) were studied for two respective years 2020-21 and 2021-22. All the crops were according to their concern seasons and irrigated with waste irrigated water. Eight heavy metals (Cd, Cr, Pb, Fe, Cu, Zn, Mn, and Ni) were studied in the grains of investigated crops. All selected four stations were specific and completely ensure the sites of contamination situated around the established industries in Sigrauli region. Grown crops were shown variable accumulation of heavy metal content. Standard acid digestion methods were employed to perform multiple residues determination through AAS. The grain samples were taken at the complete maturity of crop grains. The maximum to minimum heavy metal in respective crop order was determined. Oder of Fe and Ni was in (Oryza sativa) < (Triticum aestivum) Jowar/Sorghum (Sorghum vulgare) Maize (Zea mays). For Cu and Zn the crop order was (Oryza sativa) < (Triticum aestivum) < (Zea mays) < (Sorghum vulgare). Cd content crops order was (Triticum aestivum) < (Oryza sativa) < (Zea mays) < (Sorghum vulgare). The order for Pb content was (Zea mays) < (Sorghum vulgare) < (Triticum aestivum) < (Oryza sativa). The order of Cr in experimental crops was as (Oryza sativa) < (Triticum aestivum) < (Zea mays) < (Sorghum vulgare). The order of Mn was as (Sorghum vulgare) < (Zea mays) < (Triticum aestivum) < (Oryza sativa). The levels of heavy metals determined in the analyzed cereal samples were found to be below the permissible limit set by FAO/WHO; hence, the concentration of these heavy metals in the selected cereals analyzed, may not presently pose a health hazard in the population and can as well serve as good and dependable sources of essential trace metals to the human population.
